The safest way to clean any kind of windows virus is to work in different environment others than its originating operating system. Try virtual Ubuntu (Debian Linux) with Wubi Installer.
Here’s what wubi-installer.org has to says

Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a single click. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.

• Wubi is safe - It does not require you to modify the partitions of your PC, or to use a different bootloader.
• Wubi is Simple - Just run the installer, no need to burn a CD.
• Wubi is Discrete - Wubi keeps most of the files in one folder, and If you do not like, you can simply uninstall it.
• Wubi is Free - Wubi (like Ubuntu) is free as in beer and as in freedom. You will get this part later on, the important thing now is that it cost absolutely nothing, it is our gift to you…
